Specification of Letters Patent.

Patented Feh. F375, 1191? I Application filed January 17, 1913. SerialNo. 742,721.

To all whom it may concern Be, it known that 1, WILLIAM F. STONE, acitizen of the .United States, residing at Woodbury, in the county ofGloucester and the State of New Jersey, have invented certain new anduseful Improvements in Machines for Packaging Liquids, of which thefollowing is a specification. 1 This invention relates to machines forpackaging liquids, and particularly to a comhined bottle filling andcapping machine especially designed to fill such bottles as are used tocontain soft drinks and the like where syrup and charged water are itforced into the bottle and the bottle then capped.

' My present invention contemplates the filling of a bottle with syrupand charged Water from a single delivery nozzle and at a singleclamping. The present machine has proved to be not only a time saver,but can handle the V syrup more effectively in conjunction with thecharged water which keeps the passages flushed out and free.Furthermore, in machines of this class it has been desired that "thesniffer valve employed in exhausting the expanded gases backed up inthe. bottle neck be operated in combination with a reverse movement ofthe handle to insure that the charged liquid will be first shut oil?beforethe sniiier valve is opened. To the end, therefore, of providingmeans for filling a bottle with syrup andwater from a single'nozzle andat a single clamping, and for operating the sniiier valve in combinationwith a reverse movement of the handle, to first shut ofi' the chargedliquid before said snifi'er is opened, Ihave devise d tit) 46 my presentinvention.-

In this invention I mount a. filling head for movement on a suitablesupport and ex tend a capping plunger into said head. Theheadh'asa-plural liquid supply include5 ing a syrup pump and a charged watervalve and the arrangement is "such that the charged water is deliveredsubsequent to delivery of the syrup so that the delivery'passages'areproperly flushed at. The

so deliyeryot hoth syrup and charged Water is through a single clampingnotzle and is cheated at a'single clamping operation. A sniffingrlevice' is associated with the head and may beoperated at any time toexhaust such gases as may havelformed in spective view of the upper partof my maporting frame in which is fulcrum is pivoted a verticallymovable red the bottle. The various operating elements of the machineare successively brought into operation by an operating mechanism havmga plurality of successively active phases including a head loweringphase a bottle neck clamping phase, a pump actuating phase, and acharged water discharge phase in one direction, and having a suiiiingphase, abottle sealing phase, a bottle un clamping phase, and a headraising phas in the opposite direction.

The construction and operation of my improvements will he more fullypointed out in the specification which follows, and as illustrative ofthe invention l have sho in the accompanying drawings an emhodi mentwhich I have found practical and well adapted for the purposes intended.

Throughout specification and drawings similar charactersof referencewill denote correspondingparts.

The numeral 1 designates a suitable ,4. W i at;

treadlelever 2 to the inner o wt c clamping collar 4 is fixed upon saidr supports a bottle seat upon whic a bottle 6 retained in position bysecured to the trance. Upon the up of the frame is mounted a morals. inwhich fits a vertical plunger 9.

8is formed at its lower end with a depend-- This ring fits around thelower end of the follr wer 9 and has a slightly fiaring' tubularextension 8 into which the neck of the bottle is adapted to be thrustand capped by a cap 11 detachably retained by a cap holding ring 11fitted on the lower end of the follower. The flange 8 has a screwthreaded connection with a collar 10 provided with a pair of cars 47 towhich is pivoted a pair of links 46' whose lower ends project under thelower end of the flange 8 and bear against the flaring tubular portion 8of the compressible ring 8 These links 46 are effective when expanded tocompress the rubber ring. and cause it to tightly clamp the neck of thebottle, thus providing a water tight joint to prevent escape of thefluids. The manner in which this expansion of the links is accomplishedwill be more particularly pointed out hereinafter. The other end of thefollower passes through a sleeve 12 integral on the frame, and has ayielding bearing in the form of a spring 13 surrounding its upper endand confined within said sleeve.

' A syrup pump 14 is mounted on the frame and receives syrup from asuitable connection 15, controlled by a suitable check valve 15 anddischarging into a syrup chamber 16, controlled by a spring actuatedvalve 17 seated in a valve casing 18, and communieating with the fillingnozzle by means of a conduit 19. The charged water is admitted into acontainer 20, communicating with the conduit 19 and supplied from asuitable source. Said casing is controlled by the valve 21. The snifferor vent valve 22 is oppositely mounted, and has a connection 23 toconvey the exhausted gases into the atmosphere. The syrup and chargedwater thus enter the bottle through a single nozzle and at a singleclamping. This construction effects a saving of time, as well as Keepingthe passage flushed out and free from the gumming action of the syrup.

Journaled transversely of the frame is a spindle 24 to one end of whichis fastened a plate 25 which provides a support for a pivoted clampoperating lever 42. A crank disk 27 and a crank 28 on the handle 29 areemployed to rotate said spindle. Fast on said spindle is a cam 30,formed with a cam slot 31, terminating at one end in recesses or pockets32, in which are normally engaged the 1011s 33 on the upper end of thelink 34, the lower end of which link is pivoted to a block 35 fast onthe rod 3 and supported on the transverse web 36, of the frame 1.

Fastened to the cam 30 is one end of a valve actuating arm 37, formedwith an inclined portion or cam shoulder 38, upon its long arm, andhaving its free end bent downwardly at substantially right angles andterminating in a second cam shoulder 39, the purpose of which shouldersbeing to successively operate the charged water and sniifer valves. Asecond cam 40 is fastened to thecam 30, and is engaged by the roll 41 onone end of the clamp operating lever 42, pivoted centrally to the plate25 of the spindle, and bifurcated at its opposite end'to work over aguide pin 43 on the collar 44 of the movable head. This collar 44 isformed with wedges 45 effective when the collar is' moved, to engage therolls disk 27-of the spindle at its lower end and slotted at its'upperend. In this slot 49 a stop 50 is located. 'One end of adetachablecoupling head 51 works in said-slot, the other end of which head isdetachably mounted on the pump rod 52 of the syrup pump 14. The pump rodis guided and steadied by the angle bracket 53 fastened to the sleeve12.

The operation is as follows-Assuming the parts to be in the positionshown in Fig.

9 with the crank arm 28 raised, the link 34 will be seen to besupporting or propping up the movable head. This position is illustratedin Fig. 6. When the' handle is moved downwardly the spindle 24 isrotated, thus moving the arm 37, cams 30 and 40, and clamp operatinglever 42. The link 34 swings to the right, as shown in Fig. 8, in whichfigure the parts are in their intermediate positions. This movement ofthe link causes the cam 30 to which is fastened the cam 40, to swingtoward the right, thereby moving the arm 37 from its normal position atthe right in a direction toward the left as shown in Figs. 6, 7 and 8.This movement of the arm 37, however, is retarded by reason of theengagement, of the rolls 33 on the upper end of the link 34 with therecesses 32 in one end of the cam slot 31 of the cam .30. The cam slotand recesses thus act in the nature of an idler slot to retain the arm37 until such a time as the pump has pumped a charge of syrup into thebottle. Th erotation of the spindle 24 and ,cams tendsltoi'rock theclamp operating lever y reason of the engagement of theroll 4 the cam40. Inasmuch as the other end of said lever is fitted upon the pin 43 ofthe collar 44, the said collar is moved downwardly. This downwardmovement of the collar 44 causes the wedges thereon to ex band the upperends of the links .46, the

on one end of said lever withlower ends of which are pivoted in the earsformed 'on the collar thus contracting the lower ends of said links andclamping the compressible rings 82 about the neck of the bottle. In themean time, the link -18 has been actuated by the rotation of the crankdisk 27 to which it is fastened to reciprocate the piston rod 52 of thesyrup pump, thus pumping a charge of syrup into the bottle. Just atthetime When the pump me has completed its stroke, the valve operatingarm 37 has completed its swing and occupies theposition shown in Fig. 7.

, The rolls 33 on the link 3i now hare been disengagedcompletely fromthe. recesses 32 ot the cam '30, both cams have reached their utmostmovement to the right, the rolls are at the extreme left end of the camslot, and the clamp operating lever 42 has been rocked to tightenthering 8 on the bottle neck. il /1th the parts in this position and thecharge of syrup pumped into the bottle, the pro ecti on 38 on the valveoperating arm 37 will strike against the valve controlling the supply ofcharged Water to the bottle to admit a proper amount. The reversemovement of ,said arm 37wvill cause the other projection 39 to openthesnifi'er valve to permit the escape of the backed up'gases in thebottle, which gases prevent bottle be ing completely filled. When thebottle has been snified, the: operating arm 37 is again brought forwarduntil projection 38 'oper ates valve 21 allowing bottle to fill. In thisposition and with full gas pressure on bottle contents, the bottle isready to be capped. The capping is performed by depressing the treadle2, thereby lifting the rod 3 and moving the bottle into contact with thecap seated in the capholding ring of the yicldingly mounted follower.The

upvvard movement of the bottle seats the cap thereon, whereupon thetreadle is released and the rod 3 and bottle are lowered.

The valve actuating member 37 is now returned to its normal position,and the filled and capped bottle may then be removed from its seat andan empty one substituted.
